Are there times when it is justified to fight? For what?
Yes, when someone hits you I think its right to knock them out.
Can you fight for something without becoming violent? How can you fight peacefully?
There is no peace in fighting, not even boycotts, because those people still get a beat down and shot at.
What would you fight for? How and why?
If a person did a serious hit on me, I'd fight back. Why? Because he deserves it for touching me, and how? With my fist to his face.
